Has anyone checked out the mule posted on ebay that has a spud gun mounted on it? look at the crank pulley in the pic. I have never seen one like that on a mule.

looks like he has added a second large pulley to the crank pulley, probably to drive the alternator. Never underestimate the power of bubba.

Chuck is right it was added because a Starter-Generator was used and the larger additional engine pulley helped reduce the load while in starting mode but that pulley in relation to the starter-generator pulley is about 6-? to 1 and the engine at 3600 rpm would spin the generator about 21,600 rpm.

I installed a starter-generator on a M274 with a 4 cyl AO53 engine and had to tension the belt very tight so it would not slip on the generator pulley in start mode. I used the 2nd sheave of the original engine pulley.

The Subaru Brat Jump Seats are one of the best additions for a Mule when adding additional seating. You can fab a mounting platform that could bolt to the hand rail mounting brackets and avoid drilling through the bed making it easy to remove. Add aluminum shim stock 1/8 x 2 to the bottom of your seat platform to avoid steel to the magnesium-aluminum deck. The ones I have mounted on 2 Mules I rear faced which still allows some cargo space on the rear of the Mule. Great for a hunting vehicle take the crew out and have space to haul them and the game back.

The Spud Gun Mule appears to be a M274-A2 but has an A5 engine cover.
